Description

TECHNICAL FIELD

[0001] The utility model relates to the field of wiring harness processing device, more specifically, to a wiring harness parallel connection pressure bonding device. BACKGROUND

[0002] The wiring harness parallel connection pressure bonding device is a professional equipment for connecting and fixing multiple wiring harnesses together, which is widely used in electronic and electrical manufacturing, automobile wiring harness processing, industrial automation and many other fields. It is usually composed of a pressure bonding die, a power driving part, a positioning and clamping mechanism, and a corresponding control unit, aiming to form reliable electrical connection and mechanical fixation of the connection part of the wiring harness through mechanical pressure.

[0003] When using the wiring harness parallel connection pressure bonding device, the insulating outer skin of the wiring harness is usually made of high molecular materials such as plastic and rubber. Under the action of high-frequency vibration of ultrasonic waves and pressure friction caused by pressure bonding, these high molecular materials will undergo physical changes and then decompose to produce small molecular volatile substances, forming harmful gases. If the operating personnel are exposed to the environment containing harmful gases for a long time, the air quality in the workshop will deteriorate, which not only harms the health of workers but also may violate environmental protection regulations.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the utility model has the advantages that:

When the wire harness connection surface is contacted, part of the inner sliding vertical rod is lifted by resistance, and the remaining inner sliding vertical rod is stationary. By virtue of this differential displacement adjustment, the protective frame assembly can closely fit the wire harness profile, optimize the fitting degree of the protective surface, strengthen the protection efficiency, reduce the interference of external factors on the wire harness crimping process, the exhaust gas outer suction pipe body at the upper end of the protective frame assembly uses the external suction pump negative pressure suction force to timely suck the harmful gas generated by the crimping, efficiently prevents the accumulation of gas in the workshop, maintains the good air circulation state of the workshop, and further ensures that the working environment meets the standards.

[0018] (2) The lower part of the inner sliding vertical rod is specially designed, and the replaceable bottom accessory rod is detachably connected through the threaded inner groove.
